I got my 10.5 recently. It didn’t have yellow edging but it lacked brightness uniformity. There was a dark band that spanned across the screen, about 1/2 inch tall, right above the home button. The Apple genius noticed it right away when I brought mine in. Apple replaced it with new iPad Pro. Now my new iPP has uniform brightness but its magnets are weak (so my Apple Smart Cover goes on sloppy). Oh well, I will be upgrading to the 2018 iPP anyway so my ownership of this 10.5 will be short-lived. But I love the 10.5, it’s size is perfect for portability and my use.
